A JSObjectRef that is a function, or NULL if either body or parameterNames contains a syntax error. The object’s prototype is the default function prototype. Discussion Use this method when you want to execute a script repeatedly to avoid the cost of reparsing the script before each execut...
A“TypeError” exception occurs when a value is not of the expected type. Attempting to call a non-existent object method is a common cause of this type of exception. The following example creates an empty object named “foo” and then attempts to invoke its bar() method. Since bar() is...
myObject.foobar//"hello"myObject["foobaz"]//"world" Property vs. Method property access。是一些开发者用于区别的名称。 在其他语言,函数是属于对象(类)的,被称为方法method。 The safest conclusion is probably that "function" and "method" are interchangeable in JavaScript. 函数,方法,其实没什么区别。

当调用 location.reload() 方法时, aspx页面此时在服务端内存里已经存在, 因此必定是 IsPostback 的。 如果有这种应用: 需要重新加载该页面,也就是说期望页面能够在服务端重新被创建,期望是 Not IsPostback 的。这里,location.replace() 就可以完成此任务。被replace的页面每次都在服务端重新生成。
The syntax trees used in unified are unist nodes. A tree represents a whole document and each node is a plain JavaScript object with a type field. The semantics of nodes and the format of syntax trees is defined by other projects:
Class definitions can also have static properties and methods by defining the reserved _statics_ object://Define the class var MyStaticClass = OOPS.extend({ _statics_: { message: "Hello Static World!", getMessage: function() { return MyClass.message + " ~toString"; } } /* Other normal...
The mixin pattern (both explicit and implicit) is often used tosort ofemulate class copy behavior, but this usually leads to ugly and brittle syntax like explicit pseudopolymorphism (OtherObj.methodName.call(this, ...)), which often results in code that is harder to understand and maintain....
